thanks tim. after messing around with it some more, it is behaving differently, but still strangely. now the lower quantizer works as the upper one does, except with nothing plugged in the input it gives a steady 1.84 volts. when a signal is introduced to the input jack, it will give quantized voltages above 1.84 volts, but not below. weird.

The two signal paths share parts of the three main ICs, so I'm thinking that if they work for one section, then why not for the other, so it might just be something simple...
